The Catheter Anatomical Guidance Facilitates Ethanol Ablation of Ventricular Arrhythmias from the Left Ventricular Summit

Venous ethanol ablation (VEA) is effective for ablation-refractory ventricular arrhythmias (VAs), particularly those arising from the left ventricular (LV) summit and interventricular septum 1 .However, numerous intricate veins within this region make the accurate mapping technique-challenging 2 .Despite the microelectrode or guidewire could
